The Indian Olympic Association sent a letter to the Tokyo Olympics organizing committee complaining stricter coronavirus restrictions against its athletes and those from other countries aimed at stemming the spread of highly contagious variants are "unfair and discriminatory," according to local media.

The Indian Olympic body said that given Indian athletes will be fully vaccinated and take PCR tests every day for a week ahead of their departure for Tokyo, being barred from interacting with anyone from other countries for three days upon their arrival would be "highly unfair," according to the Press Trust of India.

"Athletes are allowed to arrive in the games village only five days before their event. Now three days will be wasted, this is the time the athletes need to be moving towards their mode to peak. Highly unfair for Indian athletes," association President Narinder Batra and Secretary General Rajeev Mehta were quoted as saying in a joint statement.
